Why are most modern constellations composed of faint stars or located in the southern hemisphere?

1 answer:

3 0

Astronomers from areas in the northern latitudes developed different constellations and maps of the sky than their southern counterparts, as faint stars weren't visible to them. In the 18th and 19th centuries, there weren't constellations in the southern hemispheres, so astronomers, instead, invented them.

The share of the liquid fresh water of the Earth that accounts for ground water is about 94.05%.
The two geological roles of ground water are given below:

It acts as an erosional agent.
It acts as a stream flow equalizer, i.e., it is a sort of storage form in order to provide sustainability to the streams during dry periods.

For about 23% of U.S fresh water is provided by ground water.
Most of the ground water is utilized for irrigation purposes.

how was the movement that led to the independence of bangladesh similar to the movement that led to the formation of pakistan

olchik [2.2K]

Both movements were based on formation of countries that are Muslim, and they were done in a military manner with violent clashes.

Explanation:

Pakistan and Bangladesh have traditionally been part of India for thousands of years. This changed when the British Empire granted independence to its South Asian colony and instead of keeping it whole it divided it, initially in two parts, later it turned out to be three. This happened both because of what was thought to be the best for the stability of the region, but also because of propaganda and movements from the Islamic world.

Unlike India, Pakistan and Bangladesh were predominantly Muslim, so in order to avoid internal conflict the British decided to partition India in accordance to religion. While this seemed that it would contribute to avoiding problems and conflicts it turned out to be the opposite.

The Indians were not happy with this and acted aggressively to the loss of territory. The Islamic movements in Pakistan and later in Bangladesh also acted aggressively. This led to large scale conflict, with millions of people ending up dead or homeless, and there was a large scale persecution based on religion.

If the earth is 4.6 billion years old, why is the oldest ocean floor only 180 million years old?

borishaifa [10]

the oldest ocean floor is only 180 million years old, because the oldest crust is destroyed at subduction zones.

<h3>What are subduction zones?</h3>

According to NOAA, tectonic plates are fragments of the Earth's hard outer layer that steadily travel across the surface of the globe over millions of years (opens in new tab). (This is a fundamental principle of the theory of plate tectonics, which holds that pieces of the Earth's crust slide across the lower mantle and carry continents with them.) According to the U.S. Geological Survey(opens in new tab), the Earth's crust and the top part of the mantle, a thick, heated layer under the crust, make up that outer layer, also known as the lithosphere (USGS). This lithosphere material curls downward into the heated mantle during subduction zones, when two tectonic plates collide and one slides beneath the other.
